What is the history of Orlando International Airport (KMCO)?
Orlando International Airport history explained: its 1942 military origins, McCoy name, MCO code, civil conversion, terminals and expansion.
Orlando International Airport grew from a Second World War military airfield into Central Florida’s principal airport. Military flying began in 1942; it became Pinecastle Air Force Base, was renamed McCoy Air Force Base in 1958, opened to joint civil use in 1964, closed as a military base in 1975 and became Orlando International in 1976.
For our Aviation & Real-World Flying readers, the crucial distinction is that KMCO was not built for Walt Disney World. Orlando’s airline traffic originally used Orlando Municipal Airport, later called Herndon Airport and now Orlando Executive Airport. The McCoy site offered the longer runways and expansion room required by jet aircraft.
Orlando International Airport history: key dates
The airport’s defining transitions were its creation as a military airfield, conversion to joint civil use and subsequent development as a major passenger airport.
| Date | Development |
|---|---|
| 1942 | Military flying begins at Orlando Army Air Field No. 2, an auxiliary field serving Orlando Army Air Base. |
| 1943 | The installation is renamed Pinecastle Army Airfield. |
| 1951 | The post-war field returns to active service as Pinecastle Air Force Base. |
| 1958 | The base is renamed McCoy Air Force Base in memory of Colonel Michael N. W. McCoy, who was killed in a B-47 accident in 1957. |
| 1964 | Orlando Jetport at McCoy begins joint civil-military operation while the Air Force remains active. |
| 1971 | The opening of Walt Disney World accelerates the region’s already-growing passenger demand. |
| 1975–1976 | McCoy Air Force Base closes in 1975. The Greater Orlando Aviation Authority is created, and the civil airport receives the Orlando International Airport name in 1976. |
| 1981 | The central landside terminal and satellite-airside system associated with Terminals A and B opens. |
| 2003 | Runway 17L/35R opens, giving KMCO four parallel north-south runways. |
| 2022–2023 | Terminal C opens in 2022, followed by scheduled intercity rail service at the airport station in 2023. |
Why is Orlando’s airport code MCO rather than ORL?
MCO preserves the name of McCoy Air Force Base; it is not an abbreviation of Orlando. ORL was already associated with the city’s original municipal airport and remains the identifier for Orlando Executive Airport.
- MCO is the IATA code used on tickets, baggage labels and airline schedules. It is also the FAA location identifier.
- KMCO is the ICAO identifier used in flight planning, air traffic control and aviation weather. The K is the ICAO prefix normally applied in the contiguous United States.
The official airport name no longer contains McCoy, but its identifiers keep that part of the site’s history visible.
How did KMCO’s terminals and runways develop?
The familiar Terminal A/B complex dates from 1981, although its airsides and internal facilities have been expanded repeatedly. A and B are two sides of the same central landside building, not two completely separate terminals; automated people movers connect that building with the satellite airsides.
Additional airsides, roads, parking and runway capacity followed as tourism and Central Florida’s population grew. The opening of 17L/35R in 2003 completed the four-runway parallel arrangement. Terminal C, opened in 2022, is a separate terminal in the airport’s southern complex rather than another side of the original A/B building.
Runway identifiers, lengths and operational details should be checked against our published KMCO charts and airport information, because a historical plan or simulator scenery may show an earlier configuration.
Did Walt Disney World create Orlando International Airport?
No. Military flying at the site started nearly three decades before Walt Disney World opened, and Orlando Jetport at McCoy was handling civil traffic from 1964. The resort’s 1971 opening did, however, produce sustained demand that helped drive the larger 1981 terminal, additional airsides and later runway expansion.
Calling KMCO “the Disney airport” therefore misses its military and early jet-age history. Tourism transformed the scale of its passenger operation; it did not create the airfield.
Can you recreate historic KMCO in a flight simulator?
Yes, but the scenery or airport file must match both the intended period and simulator. Our March 2004 FS2004 airport-layout snapshot records period gate positions shortly after the fourth runway was added, while an FS2004 recreation of KMCO’s 2008-era facilities represents a later terminal, ramp and airside arrangement.
A mistake we see constantly is treating an AFCAD as a timeless or authoritative airport chart. It reflects a particular date and author’s parking assignments, and an FS2004 file should not be assumed compatible with a newer simulator. Use these packages as period representations and compare their layouts with published airport data when planning realistic operations.
